Top 10 BIM Acronyms Explained

 

There is a growing interest in BIM and the benefits that follow this process. But, as this intelligent data presentation has English as the first language, the acronyms and vocabulary abstracted from it are a separate skill that an engineer should master.

 

Here is a list that our team prepared for you. It contains all the essential information so that you wouldn’t get confused at your next big meeting.

 

 

1. IFC “Industry Foundation Classes”

It is a data model intended to describe architectural, building, and construction industry data. It has an open and neutral file format for exchanging data and was developed by a global organization called BuildingSMART. 

Regardless of what software platform you are using, the information can be openly exchanged. 

Most software platforms will have an IFC export function or the ability to save data in IFC format.

 

2. LOD “Level of Detail”

It represents the measure of graphical or 3D information inside a data model at any point in the project. Levels of Detail and Levels of Information are together called “Levels of Definition.” 

 

3. LOI “Level of Information” 

It is the measure of non-graphical information inside a data model at a given stage. It can be framed by timetables, determinations, or other 2D documentation.

 

4. MIDP “Master Information Delivery Plan”

This is a report created from the BIM Execution Plan, setting out what data should be conveyed. The configuration ought to be described in the timescales and who needs to deliver it. Under a MIDP sit different Task Information Delivery Plans (TIDPs), which all feed into the expert report.

 

5. BIM EP “BIM Execution Plan”

A BIM execution plan is a comprehensive document that helps the project team identify and execute the role BIM plays in the various phases of construction management. Correctly built BEPs help keep teams on track by focusing on the crucial details, not necessarily micro-details, saving time for the team and the project.

 

6. EIR “Employer’s Information Requirements”

Directly at the beginning, Clients or Employers set out the data they will need in this report. It will state what they need at critical phases of the undertaking to decide what they’ll require at handover to work their new resource at an ideal level. This archive is set up, so project groups understand what graphical and non-graphical data is needed and when.

 

7. PIM / AIM “Project Information Model” / “Asset Information Model”

PIM is an information model developed during the design and construction phase of a project. The requirements for the Project Information Model are set out in Employer’s Information Requirements (EIR). It is likely to consist of a federated building information model, non-graphical data, and associated documentation.

Once the construction is complete, the Project Information Model is developed into an Asset Information Model (AIM) to be used during the operational phase.

 

8. PAS 1192 “Publically Available Specification 1192”

A series of PAS documents are set out to establish the requirements for achieving BIM Level 2. This is providing a framework for collaborative working and information requirements.

They are published by the British Standards Institution.

 

9. BEP “BIM Execution Plan”

A document prepared by the contractor shows how aspects of the project’s information model will be taken into account in carrying out the planning and implementation phases. In other words, the BEP is the contractor’s response to the requirements included in the EIR.

 

10. CAPEX “Capital Expenditure – for Capital Expenditure”

For a tradesman, this represents the cash flow to have a fixed capital investment. It is the financial commitment that goes into supporting the construction of an asset or building.

 

 

 

Expect the acronyms; you will also encounter a lot of big words. Here is an explanation for some of them.

 

  • Data Set

The model formed in graphical and non-graphical information is called a data set. As the engineers will add more details over the building’s life span, it will grow in richness.

 

  • Federate

It is a term representing all the information models being put into one. For the graphical information, software tools are used to ensure that the models are created on the same scale and with the exact coordinates.

The federated model is shared in the CDE.

It gives all parties one source of clear, structured information.

 

  • Interoperability

Different team members work in other software, and when federated, the result can also be in a different format. You need to make sure that the files can be exchanged, opened, viewed, and interrogated easily between all platforms and the pieces of data are not lost or corrupted in the process. This is called interoperability.

 

  • Originator

It is a name for the person or organization that created a piece of data in the first place. 

 

  • Attribute Data

The non-graphical data in BIM can be linked and referenced to the graphical data. That information is known as its attributes, and it is called attribute data.

 

  • Data Drop

This represents the process of presenting fixed information at a given point or milestone in a project. The PAS 1192-2 highlights a number of points in the project process when data sets can be extracted from the information model. They are called data drops.
